All Solaria modules are equipped with factory locking connecting cables.
Modules have been designed to be easily connected.
The locking
connectors are not to be disconnected under load.
The proper
procedure to disconnect the module locking connectors is as follows:
Turn off the inverter(s), shut off the module DC disconnect(s) and then
disconnect the locking connectors using an approved tool set. To re-
install, connect the module locking connectors, turn on the module DC
disconnect(s) and turn on the inverter(s).
Match the polarities of the cables and terminals when making
connections; failure to do so may result in damage to the modules and
other electrical equipment.
A properly rated and certified over-current device must be connected in
series with each module or string of modules when reverse currents can
exceed the value of the maximum protective fused value noted on the
module label. The rating of the over-current device shall not exceed the
value of the maximum protective fuse rating specified on the module
label.
All Solaria modules are factory supplied with bypass diodes located in the
junction box. These diodes protect the shaded cells within a module.
Partial shading of a single module in a string of modules causes reverse
voltage across the shaded cells. This results in current being forced
through the shaded cells causing module heating and severe power loss.
The bypass diodes provide a low-resistance current path through the
shaded cells thus minimizing module heating and array current loss.
The junction box is not designed or certified to be field accessible or
maintainable and should under no circumstances be opened. Opening the
junction box may void the module warranty.
